Problem
General problems using a SCSI drive as drive D wi th ano ther SCSI
drive as drive C.
Action
1Make sure that both standard hard disks are set to Not Installed
or No Drive Installed with your CMO S Setup program.
2Make sure that the SCSI drive that you want to use as drive D
is set to SCSI ID 1:0. Check your drive manual for information
on setting the SCSI ID for that device.
3Make sure that SCSI parity is consistently enabled or disabled
on all devices on the SCSI bus.
4Make sure that SCSI termination is set correctly on the host
adapter and the peripherals.
5If your system is running under DOS, make sure that the disk
has a DOS partition and a DOS format.
Problem
The system works erratically. It hangs, or the host adapter some-
times cannot find the drives.
Action
1Make sure that SCSI parity is consistently enabled or disabled
on all devices on the SCSI bus.
2Make sure that SCSI termination is set correctly on the host
adapter and the peripherals.
3Check cable length and integrity. The cable should be no longer
than six meters total for the entire SCSI bus.
4If the host adapter and drive LEDs remain on during a hang
condition, make sure that the SCSI drive conforms to SCSI-1,
the SCSI CCS (Common Command Set) revision or SCSI-2
specifications.
